LM358ADR2G Substitution Conclusion The LM358ADR2G matches the original AP358SG-13 in package, gain-bandwidth product (1 MHz), input bias current (45 nA), and supply voltage range (3V to 32V). However, critical differences exist. The LM358ADR2G features a standard (non-differential) output, whereas the AP358SG-13 provides a differential output. In circuits requiring differential signal drive or enhanced noise immunity, the LM358ADR2G cannot directly offer complementary output characteristics, which may lead to circuit functional failure. Furthermore, its supply current is higher (total ~1.6mA vs. the original 1mA), increasing power dissipation and potentially impacting battery-powered or low-power applications. If the original application does not rely on differential output and can tolerate slightly higher power consumption, the LM358ADR2G can serve as a substitute; otherwise, it is not viable. LM358ADRG4 Substitution Conclusion The LM358ADRG4 is similar to the original AP358SG-13 in package, input offset voltage (2 mV), output current (40 mA), and supply current (total ~1mA). The primary differences include: its output is standard (non-differential) versus the AP358SG-13's differential output, which may cause incompatibility in differential signal processing applications; its gain-bandwidth product is lower (700 kHz vs. 1 MHz), reducing bandwidth and high-speed performance and potentially affecting frequency response; its supply voltage range is slightly narrower (max 30V vs. 32V), limiting suitability for higher-voltage scenarios; and its input bias current is lower (15 nA vs. 45 nA), which is beneficial for high-precision applications. If the original circuit does not require a differential output and the bandwidth and voltage range are acceptable, the LM358ADRG4 can be used as a substitute; otherwise, it is not feasible.
